This video introduces a recipe for making a fluffy chiffon cake using only three ingredients (eggs, sugar, and rice flour), without using any wheat flour, butter, or milk. Instead of a professional chiffon cake pan, it uses a mold from a 100-yen shop, and the simple process of mixing and baking ensures a professional-looking result without failure. The video also provides detailed explanations of how to whip the meringue and mix the ingredients, making it an easy gluten-free dessert for beginners. A method using a rice cooker is also shown as a trial run, but this is presented as an example of failure.
